从Play商店升级应用程序后，数据存储崩溃。最近我从共享首选项迁移到数据存储。这仅发生在像素 5 中，而不发生在 android 9 中。

以下是此崩溃的日志。

您的 proto 缓冲区文件很可能已损坏。

解决此问题的一种方法是将损坏处理程序添加到数据存储的创建中。

val context:Context = ... // your context 
val corruptionHandler = ReplaceFileCorruptionHandler<Preferences> {
    mutablePreferencesOf(
       // recover preferences here
    ) 
}
val dataStore = context.createDataStore("data_store", corruptionHandler)
